No operating system launch is without a few bugs, but it seems like iOS 7 has had more than it's fair share of blunders. From iMessages not working to lock screen exploits, here are some of the biggest bugs, and how you can fix them.

iMessage Doesn't Deliver Messages

If there's one thing you want from your phone it's the ability to send and receive messages. Unfortunately, for a number of users, iMessages isn't delivering messages in iOS 7. That means texts are essentially going nowhere. That's a pretty big bug, and while Apple says it's working on a fix in the next software update, you can fix the problem now. Head into Settings > General > Reset > Reset Network Settings. This should get those messages delivered. If it doesn't work, TUAW recommends a quick reboot.

Lock Screen Vulnerabilities Give People Access to Your Info

iOS 7 has had a few lock screen vulnerabilities that give anyone access to your data even if they don't know your passcode. Thankfully, all you need to do to fix the original bugs is update to iOS 7.0.2. However, the most recent bug (in the video above) allows people to access your phone on the newest firmware. While that's not exactly the worst thing in the world, you can keep it from happening by disabling Siri on the lock screen. Head into Settings > General > Passcode Lock. Then under "Allow access when locked" disable Siri.

Some Apps Constantly Log You Out

Right after launch, a number of iOS 7 users complained about apps like Mailbox and Snapchat repeatedly logging them out of the app. It turned out the problem was iOS 7's new background app refresh feature. Most apps have been updated to either remove the feature or work properly with it, but if you're still having problems, head into Settings > General > Background App Refresh and disable any apps that aren't working.

Audio Apps Crash When You Get a Call or Text

Right before the launch of iOS 7, Audiobus sent out emails to its users warning against upgrading to iOS 7 because music apps were crashing a lot on iOS 7. The most problematic bug happens when you're using an audio app and someone calls you. When that happens, the app crashes and loses all your data. Apps are getting updated to work properly with iOS 7, but the bug still remains in a lot of recording and music apps. Currently, your best fix right now is to enable Airplane Mode while you're making music. Just open up the Control Center (swipe up from the bottom of the screen) and tap the airplane icon.

The iPhone 5s Accelerometer Isn't Very Accurate

This problem is specific to the iPhone 5s, but it's a big one. As Gizmodo reports, a number of iPhone 5s' have screwy accelerometers. This means the compass, gyroscope, and level aren't working properly. That's bad news for gamers and anyone who uses an app with the accelerometer. It's still a bit unclear whether this is a hardware problem, a software bug on the 5s, or both, but users over on MacRumors are trying to figure it out. For the time being, your best bet to fix this problem is to exchange your phone for a new one at an Apple Store.

Since the iPhone 5S landed in the hands of new owners a few weeks ago, there have been reports that …

Chrome's Incognito Mode Reveals Your Private Browsing

While it's not exactly a problem with iOS 7 itself, Chrome's most recent iOS 7 compatibility update borked incognito mode in Chrome. Incognito mode in Chrome always saves some data on iOS, but now if you search for something in incognito mode in iOS 7 it's also showing up when you're not in incognito mode. This could prove embarrassing if you're not careful. The fix? Unfortunately the only thing you can do is stop relying on incognito mode for now while you wait for an update.
